Electronic electroplating wastewater recycling advanced treatment technology

The invention relates to an electronic electroplating wastewater recycling advanced treatment technology. The technology uses a large amount of rinse-wastewater with heavy metals in the production process of the electronic electroplating industry as the main object, adopts a combined technology of pH adjustment-microfiltration membrane treatment-pretreatment-reverse osmosis membrane treatment, is mainly characterized by the joint application of DF membrane technology and RO membrane technology and can achieve the aim of reusing wastewater and reducing the emission of heavy metals; and the reuse water reaches the production demand of process water, thus saving the fresh water consumption of the industry, effectively reducing the production cost of the industry, solving the pollution problem of heavy metals, increasing the clean production level of the electronic electroplating industry and having remarkable social environmental and economic benefits.
